International Alliance for Interoperability (IAI)

Overview: The International Alliance for Interoperability (IAI) promoted effective means of exchanging information among all software platforms and applications serving the AEC+FM community by adopting a single Building Information Model (BIM). The Alliance represented diverse constituencies, including architects and engineers, research scientists, commercial building owners and contractors, government officials and academia, facility managers, software companies, and building product manufacturers. The Alliance defined, promoted and published specifications for Industry Foundation Classes (IFC) as BIM and as a basis for AEC project information sharing through the project life cycle across disciplines and technical applications. IFC BIM were published in the EXPRESS language for software development and in eXtensible Markup Language (ifcXML) for eCommerce and Internet purposes. AecXML, derived from the IFC BIM, was also promoted by AIA and developers were encouraged to extend the IFC BIM through collaboration with IAI. *Now BuildingSmart
